Battle Against a True Hero is the 98th track from the Undertale soundtrack. It plays during the fight with Undyne the Undying. This rhythmic fast-paced battle music is one of the highlights from the soundtrack and this sheet music and arrangement is sure to please any audience! Melodies from Battle Against a True Hero are also used in Ruins and Alphys. There is an interplay between two distinct rhythmic patterns in the middle section, which is a very catchy and exciting part!
